Now when my players login (using vault 1.2.0 at the moment) they get a spam addition to motd of:
"vault 1.2.2 is out! You are running 1.2.0
Update Vault at: link"

Ok who's "bright" idea was it to spam player's clients with update info? Having it in console is great, but telling players is GOING WAY TOO FAR.

Now how to stop the spam?

it only notifies players with vault.admin - sounds like you are giving players a lot of permissions.

I'd throw out one more comment on it.

I am happy that you are maintaining this plugin, but if you are planning to release every few days, do we need to have the console spammed every 30 minutes that there is a new version out? How about one check at server start?
